Even AIs which have existed for years and been "perfected" are very noticeably not-human. Though they do look believable from far away, up close they are still in the uncanny valley. For instance Siri and Google Voice: they are clearly understandable but they sound noticeably different than real people. Or Stable Diffusion which will supposedly put real artists out of business. It is definitely viable for stock photos, but I can usually tell when an image was made by Stable Diffusion (artifacts, incomplete objects, excessive patterns). thispersondoesnotexist.com faces can also be spotted, though only if I look closely. If they are a profile pic I would probably gloss over them. In fact, I bet you can make an ML model which very accurately detects whether something was made by another ML model. Actually that's a good area of research, because then you can make a deepfake model which tries to evade this model and it may get even more realistic outputs... Ultimately I think we will see a lot more AI before we start seeing truly indistinguishable AI. It's still close enough that the ethical concerns are real, as people who don't really know AI can be fooled. But I predict it will take at least a while before a consensus of trained "AI experts" can't agree on authenticity.
